By the 1920s, the family had relocated to Los Angeles, and by 1930, they lived in Beverly Hills.
By 1956, Claude Beelman & Associates officed at 7421 Beverly Blvd., Los Angeles 90036.
It is the zig-zag moderne Eastern Columbia Building, however, with its facade of turquoise green terra cotta tile, ornate clock tower, art deco lighting, fixtures, signage and architectural detail that is Beelman's most recognizable work.
In 2006, the Eastern Columbia Building was converted from office space to loft live/work spaces by the Kor Group and is now one of the most desirable loft buildings in Downtown Los Angeles.
On May 12, 2023, Beelman was posthumously awarded an Honorary Doctor of Architecture from Woodbury University in Burbank, California.
